This is something I found very interesting, we have no idea why we start writing with a pencil, why we do not use the pen in the beginning years of life,  then it would have been so easier isn’t it?, We need not put effort to practice writing with the pen as we do now.  In the initial years of our childhood, we make lots of mistakes, so the pencil is easy to erase, during these years we always have our guardians or parents or mentor with us, constantly watching on us and correct our mistakes.  As we grow young we will have some kind of knowledge about what should do and what not, youth will show confidence and tendency to move out their own, some may take the opportunity to go out of the shade of guardians and parents, and explore.   One important lesson we forget during this journey that mistakes made in adulthood is hard to erase, not to say about the remaining years of life.  We have a whole life before us to learn and the process of learning never ends.  So, when we make mistakes deliberately, we should think twice.  The personal intelligence is put into practice the things we have learned for personal growth,   mistakes are unavoidable, but hung on the same is not a wise idea.
